How can we improve performance in Windows Server?

← Performance

ntdsperf.dll missing on Server 2019 LTSC

built a new 2019 standard server with desktop experience, patched fully, add it as a new domain controller in an existing domain, all goes well but the reason I did was someone in forums getting perflib 1023 error referencing ntdsperf.dll and is no where on system. Same for my new one, no where on system yet there is a reference to it HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Performance. I don't get the error because I have no counters running yet the missing file seems problematic.

    To fix run this from cmd prompt (run as administrator)
    lodctr /e:C:\WINDOWS\system32\ntdsperf.dll

    Then run:
    lodctr /r

    This should then result in the following being displayed:
    "Info: Successfully rebuilt performance counter setting from system backup store"

    Hopefully no more errors in the event log from that point

    I'm getting the exact same error trying to promote a 2019 member to a DC.
    Also getting verification of replica failed.The forest functional level ... must be server 2008 or higher. (THE FFL was already 2008 and it didn't work P.S. I have a 2012 R2 DC currently. I raised the FFL to 2012 R2 and I am still getting the same error about the FFL need to be 2008 or higher.

    getting:
    Application 'C:\Windows\System32\wsmprovhost.exe' (pid 4712) cannot be restarted - Application SID does not match Conductor SID..

    FYI - the local domain is single label so
    TO JOIN the 2019 server to the (I also have to do this with Windows 10 workstations) domain I had to FIRST DO:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters
    Locate AllowSingleLabelDnsDomain. If the key AllowSingleLabelDnsDomain does not exist:
    Edit, New, DWORD.
    Write AllowSingleLabelDnsDomain as key name, and ENTER.
    Double click AllowSingleLabelDnsDomain.
    Set the Value to 1.

    I have the exact same error along with a 2019 domain control.
    Have you found a solution to this yet?
